The housing unit 102 may house therein a wireless power transmission unit 105, a processor 106, a pressure sensing unit 107, a communication unit 110, a battery unit 111, and a storage unit 112.

The frame part 102 may be provided with a rail groove 102a and a fixing protrusion 102b to be detachably coupled with the base part 101.

Specifically, when the rail groove 102a is detachably coupled to the base portion, it may be formed at the center of the lower portion of the housing portion 102 so as to guide the detaching direction by being fitted from the lower portion side of the housing portion 102. The track groove 102a is inserted with a track protrusion 101a for guiding.

The housing unit 102 may be fitted from the upper side toward the lower side, and may further include a receiving groove 102c for receiving the 2 nd rotation shaft 104e of the rotation unit 104 and the 2 nd rotation sensor unit 109.

The receiving groove 102c may have a circular cross section, and a projection may be formed adjacent to the upper surface at a height thereof to allow the rotary plate 104d of the rotary part 104 to be fitted thereto.

At this time, the inner center of the receiving groove 102c may be formed with: and a rotation groove 102d rotatably coupled to the other end of the 2 nd rotation shaft 104 d.

That is, the 2 nd rotation shaft 104e is accommodated in the accommodation groove 102c in a vertical state, has one end coupled to the center of the lower portion of the rotation plate 104d and the other end hinge-coupled to the rotation groove 102d, and rotates with the rotation of the rotation plate 104 d.

The holder portion 103 is formed in a partially cut loop shape and is held by a user of the portable terminal 10. Specifically, when the user inserts and holds a part of the body (finger) inside the holder 103, the 1 st rotation (R1) or the 2 nd rotation (R2) is performed by the force applied by the user.

Here, the rotation shaft is in a horizontal state with respect to the upper surface of the frame part 102 in the 1 st rotation (R1), and is in a vertical state with respect to the upper surface of the frame part 102 in the 2 nd rotation (R2). At this time, the rotation axis of the 1 st rotation (R1) is the 1 st rotation axis, and the rotation axis of the 2 nd rotation (R2) is the 2 nd rotation axis. Further, the 1 st rotation axis may be the same as the 1 st rotation axis 104b, and the 2 nd rotation axis may be the same as the 2 nd rotation axis 104 e.

In the holder portion 103, one end of the cut may be coupled to one end of the 1 st rotating shaft 104b of the rotating portion 104, and the other end of the cut may be coupled to the other end of the 1 st rotating shaft 104b of the rotating portion 104.

One side and the other side of the rotation part 104 may be coupled with the holder part 103 and the chassis part 102, respectively, to facilitate the rotation of the holder part 103 with respect to the portable terminal 10.

Therefore, the rotating part 104 may include a rotating body 104a, a 1 st rotating shaft 104b, a 1 st pair of rotating covers 104c, a rotating disk 104d, and a 2 nd rotating shaft 104 e.

The 1 st rotation shaft 104b is rod-shaped, one end thereof is coupled to one end of the holder 103, the other end thereof is coupled to the other end of the holder 103, and when the holder 103 rotates, the rotation shaft may be the 1 st rotation shaft of the 1 st rotation (R1), and the 1 st rotation (R1) and the upper surface of the frame part 102 are in a horizontal state.

The rotary covers 104c are each formed in a disk shape with a center thereof penetrated, and the penetrated portions are inserted into both ends of the 1 st rotary shaft 104b to support the 1 st rotary shaft 104 b.

The rotary plate 104d has a disk shape and closes a lower portion of the rotary body 104 a. At this time, a portion of the lower portion of the rotating body 104a and a portion of the lower portion of the rotating disk 104d may be placed on bosses formed in the receiving groove 102 c.

The 2 nd rotation shaft 104e is rod-shaped, and has one end coupled to the center of the lower portion of the turntable 104e and the other end coupled to the rotation groove 102d of the housing part 102, and can be the 2 nd rotation shaft of the 2 nd rotation (R2).

The wireless power transmission section 105 wirelessly transmits the power charged in the battery section 111 to the portable terminal 10 by the control of the processor 106.

For this purpose, the wireless power transmission unit 105 may include a wireless power transmission coil and a power conversion circuit.

Also, the wireless power transmission manner of the wireless power transmission part 105 may not be limited as long as the power charged by the battery part 111 is wirelessly transmitted to the portable terminal 10.

The processor 106 may control operations of the wireless power transmission part 105, the pressure sensing part 107, the 1 st rotation sensing part 108, the 2 nd rotation sensing part 109, the communication part 110, the battery part 111, and the storage part 112.

The processor 106 may include more than one Core (Core, not shown) and an image processor (not shown) and/or a connection channel (e.g., a bus, etc.) to send and receive signals to and from other components.

In one embodiment, the processor 106 executes one or more instructions stored in the storage unit 1112 to implement the operation of the cradle apparatus 100 for a wirelessly rechargeable portable terminal.

Specifically, the processor 106 determines the output of the wireless power based on one or more of the mounting information indicating whether the base unit 101 mounts the mount unit 102 and the rotation information indicating the rotation state of the holder unit 103, and controls the wireless power transmitting unit 105 so as to transmit the wireless power corresponding to the output determined by the portable terminal 10.

The processor 106 may determine the fitting information based on the protrusion pressure input to the fixing protrusion. Wherein the protrusion pressure can be detected by the pressure sensing portion 107. In the process of inserting the rail protrusion 101a into the rail groove 102a, the fixing protrusion 102b is pressed by the rail protrusion 101a at the end of the insertion and is inserted into the fixing groove 101b, and then the pressing is released.

At this time, the pressure sensing portion 107 can detect: the fixing boss 102b is pressed by the rail boss 101a at the moment of the boss pressure.

In contrast, in the process of separating the rail protrusion 101a from the rail groove 102a, the fixing protrusion 102b is pressed by the rail protrusion 101a at the initial stage of separation, and then the pressing is released.

With the above-described procedure, when the protrusion pressure is not detected after the processor 106 detects the protrusion pressure above the preset standard pressure for the preset standard time or more, the previously determined assembly information may be confirmed, and the assembly information opposite to the confirmed previously assembled information may be determined.

For example, the processor 106 may determine the assembly information so as to show that the base unit 101 is assembled with the frame unit 102 when the previously determined assembly information shows that it is not assembled.

In contrast, the processor 106 may determine the fitting information so as to show the released base part 101 fitting the machine frame part 102 when the previously determined fitting information shows that fitting has been performed.

Also, the processor 106 may include the 1 st rotation angle of the holder part 103 in the 1 st rotation (R1) and the 2 nd rotation angle of the holder part 103 in the 2 nd rotation (R2) in the rotation information.

Among them, the 1 st rotation sensor part 108 can detect the 1 st rotation angle of the holder part 103 in the 1 st rotation (R1), and the 2 nd rotation sensor part 208 detects the 2 nd rotation angle of the holder part 203 in the 2 nd rotation (R2).

The processor 106 determines to shut off the output of the radio energy when the fitting information indicates that the fitting is made and the rotation information indicates the 1 st rotation state. The fit information indicates that the radio is fit, and the rotation information indicates the 2 nd rotation state, the processor 106 decides to release the output of the radio power.

The 1 st rotation state may be when the 1 st rotation angle and the 2 nd rotation angle are included in a preset 1 st standard angle range and a preset 2 nd standard angle range, respectively. The 2 nd rotation state may be when the 1 st rotation angle and the 2 nd rotation angle are included in a preset 3 rd standard angle range and a preset 4 th standard angle range, respectively.

For example, the preset 1 st standard angle range may be 30 ° or more and 150 ° or less. The preset 2 nd standard angle range may be 80 ° or more and 100 ° or less, 170 ° or more and 190 ° or less, 260 ° or more and 280 ° or less, and 350 ° or more and 10 ° or less.

In contrast, the preset 3 rd standard angle range may be 0 ° or more, less than 30 °, and more than 150 °, 180 ° or less. The preset 4 th standard angle range may be 360 deg. all around.

That is, in the processor 106, when the cradle unit 103 is in the 1 st rotation state, the wireless charging is cut off, and when the cradle unit is in the 2 nd rotation state, the wireless power transmission unit 105 is controlled to perform the wireless charging.

Through the above process, when a user watches a video, etc., rotates the cradle portion 103 or is in a user environment where power consumption is severe, wireless charging causing the portable terminal 10 to be scalded may be cut off to prevent overheating of the portable terminal 10.

The 1 st rotation sensing part 108 can detect the 1 st rotation angle of the holder part 103 in the 1 st rotation (R1).

For this, the 1 st rotation sensing part 108 may include a 1 st rotation support rod 108a and a plurality of 1 st rotation sensors 109 b.

The 1 st rotation support rod 108a has a rod shape, and the 1 st rotation shaft 104b may be formed to be protruded in a direction perpendicular to the longitudinal direction of the 1 st rotation shaft 104 b. The 1 st rotation support rod 108a may rotate together with the 1 st rotation (R1) of the 1 st rotation shaft 104 b. The 1 st rotation support rod 108a may be made of a flexible conductive material.

The plurality of 1 st rotation sensors 108b are rounded to contact the ends of the 1 st rotation support bars 108b and are spaced apart by a given interval. The ends of the 1 st rotation support rod 108b are inserted into the respective centers to form a temporarily fixed sensor slot.

The 1 st rotation sensors 108b may have different resistances, respectively. Thus, the processor 106 may receive an electrical signal (a current signal or a voltage signal) transmitted from any one of the 1 st rotation sensors 108b corresponding to the resistance value of the 1 st rotation sensor 108b contacting the 1 st rotation support rod 108b, and convert to the 1 st rotation angle based on the electrical signal corresponding to the resistance value.

The 2 nd rotation sensing portion 109 can detect the 2 nd rotation angle of the holder portion 103 in the 2 nd rotation (R2).

For this, the 2 nd rotation sensing part 109 may include a 2 nd rotation support rod 109a and a plurality of 2 nd rotation sensors 109 b.

The 2 nd rotation support rod 109a is rod-shaped and may be formed to protrude from the 2 nd rotation shaft 104b in a direction perpendicular to the longitudinal direction of the 2 nd rotation shaft 104 b. The 2 nd rotation support rod 109a may rotate together with the 2 nd rotation (R2) of the 2 nd rotation shaft 104 b. The 2 nd rotation support rod 109a may be made of a soft conductive material.
